Application filed October 30, 1919. Serial No.` 334,435.

To all 'whom it may concern.'

Be it known that I, CLARENCE L. HARDY, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Nozzles; and

.I do declare the following to be a full, clear,

and exact description of the invention, such as will enable othersskilled in the art to which it 'appertains to make and use the same.

This invention relates to improvements in hosenozzles, and it has moreparticular reference to a fire hose nozzle" such as used in connectionwith iire engines; although it is not to be restricted to such use.

The principal object ofthe invention is to provide a nozzle* ofthe abovelmentioned type. in which-the construction is such that friction betweenthe working parts is greatly reduced, thereby preventing excessive wearbetween the parts and prolonging the life of the valve.

lAnother object of the invention is to provide a nozzle which includesan adjustable valve seat, that is, o-ne which is so constructedand'arranged that any" wear between itself and the valve may be readilytaken up.

A A further object of the invention is to provide a nozzlev of the abovementioned charactenwhich is simple in construction, highly effective andeficient in use, strong, durable, and absolutely fluid-tight.A

Other Aobjects and radvantages of the iiivention `will become apparentduring the course of the following description.

In the accompanying drawings forming a part of this Specification and inwhich like numeralsl are employed to designate like parts'throughout thesaine,

V,Figure 1 is an elevation of a nozzlevconstructed in accordance'with myinvention.

,Figf2 is a. central longitudinal sectional Figs. fand 4 are sections ofthe plane of Fig. L5 is a detail perspective view of the rotary valve,packing ring Aand packinglring retainingewasher.

Fig. 6v is a view illustrating the manner in which the handle is mader`In thel drawings, wherein for the purpose of illustration is shown. apreferred embodiment of my invention, the numeral 1 desigiiates.` avalvecasing or body showing a longitudinal tapered bore i extendingtherethrough and intersected by a substantially cylindrical valvechamber 2 in which a cylindrical rotary valve or turn-plug 3 kisjournaled. One of the ends of the valve chamber is open as shown and acap or other suitable closure 4 which has its inner. face beveled isscrew threaded therein and serves to to close the valve .chamber whenthe nozzle is in use. This cap l is removable as is obvious, and inorder to facilitate such removal it is provided in its outer face withspanner recesses 5 so that a suitable wrench may be effectivelyemployed. The rotary valve 3 is provided with a pair of oppositelydisposed stub axles or valve stemsl 6 and 7. The shorter one 7, isseatedin a socket 8 in the casing 1 andthe longer one 6 extends through avalve stemV opening 4a in the cap 4 and outwardly lbeyond the same. A.por-

10 serves to support the U-shaped valve actuthe body member 1 and `ispreferably cast integral therewith, it being in axialalinement with theaxle 6. The handle 11 includes a pair of eyes 12 and 13 `and the. eye 12is rotatable'around the axle 10, whilethe eye 13 is noncircular andcoacts with or engages the flat face portion 9 of thek shaft 6 therebypermitting the valve 3 to be opened and closed, as is obvious. I desireto make this handle of two parts to permit it to be readily placed inVactuating position. To this end it will be seen that each of theseVsections is substantially L-shaped and their meeting ends 11a and 11?are detachably connected together in overlapping relationship by meansof screws 11c (Fig. 6). InV addition to the tapered transverse passagewhich extends through vthe valve and registers with the longitudinalborein the casing 1 when the valve is open, the valve is also provided inone of its ends with a pacln'ng retaining recess 141, the centralportion of which is inwardly beveled as at v15. This recess serves toreceive Va flexible Y tion of the last named axle is provided with aflat. f ace portion as indicated at 9 and thisaxle in conJunction with asimilar stub axle insure against leakage, I drill aperturesor waterpassages 18 in the recessed end of the valve 3,' andthese aperturesafford communication between the recess 14 in the valve and transversepassage through the valve; and water under pressure within the valvepasses through these openings and A'forces the packing ring 16 tightlyagainst chamber 2 sulliciently large to permit a space to be formedbetween its inner surface and the periphery of thevalve 3. Consequently,friction between these parts will be entirely eliminated and the weargreatly reduced.

'Inasmuch as a great amount of wear between the valve and its seat wouldotherwise occur, I employ an adjustable and removable cylindrical valveseat 19 which is fitted in the longitudinal bore of the body member 1.To this 'end' it will beseen that I provide the casing 1 withanexternally and internally threaded portionv as shown at 2O and 21. A

'nozzle 22 lis threaded onto the externally threaded portion 20. Thevalve seat 19, has its inner end 23 shaped to bear tightly on thecylindrical surface of thefvalve 3', and it is provided "on its oppositeor outer end with an annular flange 24 which isdisposed in the enlarged,portion of the bore. A ring nut 25 is engageable 'with' the 'internal'threaded part 21 of the bore, and between this nut and the flange 24isa resilient packing ring 26.' VHence, it'. will be seen that f'whencontacting portions ofthe valve and valve seat become worn,fit will benecessary only to screw the nut 25 inward, thereby moving the partstightly together and taking up all wear as it occurs. I also wish to point out that by positioningl the packing .ring

j 26 between the lange 24 and the nut 25 I "greatly reduce frictionbetween the 'valve and its seat, as this` construction permits the valveseat to yield slightly.

u It` will be seen that all the parts of my valve are easily and readilyremoved for repairing, etc., andthe constructionissuch Vthat there isaminimum amountof Wear betweenthejparts thereof; it is absolutelyVfluid-tight and the parts j are exceedingly VVsimple in constructionand .comparatively inexpensive to manufacture. j

f The use and operation of the device. is believed to beunderstood,therefore, further 'description is deemed unnecessary.

Itis to' beunderstood that the forin of my finvention herein shown'anddescribed is to be taken as a preferred form of the same andthatvariouschanges in the shape, size,

and arrangement of parts may be resorted to without departing from-thespirit of the-invention or the scopeof the subjoined claims.

Having thus described my invention, I
